Multiple instances of same computer connected (some times)...

So, I finally fixed (most) of the issues I was having with iCloud and email by hand tweaking my way through ~./Library/Preferences/com.apple.[etc]...
The only weird thing that remains is that sometimes I get a dialogue box that pops up saying (not verbatim), "COMPUTERNAME is now connected to iMessage, FaceTime, etc if you have recently connected, you can ignore this.". Sometimes it says, "COMPUTERNAME (1)" is also connected.
The HOSTNAME is set to COMPUTERNAME only. (Not actually, "COMPUTERNAME", but using that as example.)
Is there a cache somewhere that could be causing this "COMPUTERNAME (1)" to randomly pop up at times?
Sorry that I'm not being verbatim, but I'm really lazy to get the exact wording at the moment.
I just started using Mac's (love 'em), but I have several decades with PC's, including with GNU/Linux..
Note: If it makes any difference, I am running Yosemite (Beta) on this particular Mac.
Thanks!

Multiple Instances of Same Computer on Network

I am having an issue with my MacBook Pro. When I open my finder it shows the same computer 14 times under shared. I only have one computer on the network. I tried to include a screenshot of the problem but I couldn't get the picture to upload.
I am running OS X 10.10 and I don't think this issue was happening before I upgraded.
Any help would be greatly appreciated. Let me know if anybody needs more info.

Can we have Multiple Instance on same Node in Oracle 10g RAC

Hi All,
I am planning to implement the RAC in Oracle 10g.Before that i have one doubt regarding RAC.
My question is "Can we create multiple Instance on Same node(Server) ?"
is it possible.
Any ideas or thoughts would be apperciable.
Thanks in Advance.
Anwar

This is where it is important to keep the separation between 'database' and 'instance'.
A database is the set of files that contains the data (and the redo, control files, etc). A database does nothing by itself, other than take up lots of disk space.
An instance is theCPU cycles (running software) and the memory to control the database.
In Oracle RAC, you can have as many instances controlling one database [at the same time] as you want (within reason). Each instance must be able to access the disk(s) that contains the database.
These multiple instances can be on the same computer (effectively taking up a lot of server memory and CPU for nothing) or they can be on separate computers.
If they are on separate computers, the disk subsystems must be able to be shared across computers - this is occasionally done using operating system clusterware and is the main reason why clusterware is required at all. (This is also the toughest part of the pre-requisites in setting up a RAC and is very vendor dependent unless you use ASM.)
These instances need a communication connection to coordinate their work (usually a separate network card for each computer) so they do not corrupt the disk when they are trying to access the same file, and possibly the same block, at the same time.
In a RAC configuration, instances can be added, started, running, stopped and removed independent of each other (allowing a lot of high availability) or can be started and stopped as a group.
Each instance gets it's own SID, which is in no way any different than a non-RAC SID. It's just the name of a service that can be invoked. The neat thing is that the SID
a) helps the DBA keep things straight by lettiung us talk about 'instance A' (the Oracle software to be running over on computer A) vs 'instance B' when starting, stopping and managing;
b) helps the application by providing targets that can be listed in the TNSNAMES.ORA [against one service alias], which is used by ORacle Networking to provide automated load balance or failover (instance/SID a is not available, I guess I'll try the next in the list)
Hope that helps the concept level a bit.

Running multiple instances from same oracle home

Hi Gurus,
I am preparing for OCA 11g examination. I had a question about running multiple instances from same oracle home. While reading the book I came across a statement about database control which says "If there are several database instances running off the same Oracle home, then each will have its own Database Control instance".
Now I assume that this statement implies multiple instances accessing the same physical database (which as per my knowledge can happen only in case of a RAC).
I am not able to understand how exactly can you have multiple database instances in a single oracle home. I have installed Oracle 11g on my computer whose oracle home is +"D:\oracle\product\10.2.0\db_1"+; now this directory houses all the binaries (executables and folders like admin,bin, etc) for the oracle instance that I have installed (the instance name is ocp1). Now if I am to install or create another Oracle Instance (say ocp2) in the same home, wont there be a conflict of binaries of the two instances in the same home ?
Basically,it makes sense if db_1 folder is further split into multiple folders, one for each instance (for example, one for ocp1 & one for ocp2); each of these folders will then contain the binary files, libraries,etc for its own instance; but, this is not the case, here db_1 houses all the binaries directly under it ...
The other question which stems from the statement I mentioned above is that if having multiple instances running from same oracle home accessing the same physical database, can this arrangement be called RAC at all; or does RAC dictate that you cannot have multiple instances that are accessing the same database have to be installed on physically separate machines and so you cannot have two RAC instances (accessing same physical database) installed on the same computer ??
I hope my questions are not too much confusing ... !!
Cheers,
Sudripta

Hello,
"If there are several database instances running off the same Oracle home, then each will have its own Database Control instance".This is true, and also means each instance will have its separate database (i.e. dbf files etc.) & separate DB Control. Usually in this case you create several instances on the same node.
Now I assume that this statement implies multiple instances accessing the same physical database (which as per my knowledge can happen only in case of a RAC).You are correct about RAC where several instances (usually running on separate nodes) access the RAC.
More info:
1 Oracle Home - 1 Database - 1 SID is possible.
1 Oracle Home - Many Databases - Many SID is possible.
1 Oracle HOme - 1 Database - Multiple SID is possible and this is called RAC.

How to use/sync single data (file) across multiple instances of same application

Currently we have an application (a diagram editor), that have the ability to save and load (serialize) its state in a xml file.
Now we want this application to behave like Microsoft OneNote application. Where multiple users have the ability to access the same file.
Later we may also need to enhance with other things like, (1)what is changed and who changed it, (2)option to resolve conflicts if any.
I came to know about sync framework to resolve this. so far, i have not tried it.
All i want is,
Virtually single file should be edited by multiple instances of same application.
We need a dll (sync framework) that does following
It takes complete responsibility of file handling.
Using this dll, each instance of the application will notify their own changes.
Each instance of the application should have the ability to detect the changes that is recently made (when, who, what are the changes).
My question:
Will sync framework be suitable for this requirement?
If so, is there a demo application that represents this?
- Jegan

Seems like I have found the solution.
In the taskflow there is a property named data-control-scope and I set it to isolated instead of the default (shared) and this seemed to do the trick.
I can now have two instances of the same taskflow running with different ApplicationModules
Cheers,
Mark

How to open multiple instances of same form thru menu items

i'm not able to open another instance of the form.....if i want to open multiple instances of same form ...what should i do???

Hi Shenaz,
To open multiple instances of the same form you need to set a different FormUID to each form you open.
So lets say your FormType is MyFormXPTO. You need can set the FormUID as MyFormXPTO_1, MyFormXPTO_2, and so on.
If you need a code samples, take a look at this post.

Help! syncing multiple ipods on same computer!

i will soon have two different ipods syncing to the same computer. how can i keep libraries separate so that my brother's music doesn't show up on my ipod and my music doesn't get synced to his?
iPod Video 30GB Windows XP

There are basically two methods for managing multiple iPods on one computer. See here:
Method 1 - Create different Windows users accounts for each iPod on this computer.
Method 2 - Create a playlist in iTunes for each iPod.
To make Method 2 work, connect one of your iPods, and click on it in the left-source panel.
Under the "Music" tab, and set your option for a specific playlist(s) under the "Sync Music" option.
Do the same with your other iPod; not connected at the same time as the other one, though.
For more details on this matter, check out Apple's Support article about it:

I hope that helps you.

Multiple instance of same mac on network

Hello,
Running OS X Yosemite, I've noticed multiple instances of the same mac appearing on my home network. Has anyone else encountered this and know of a way to fix it? Currently, I have to try more than one instance before I find the "correct" icon to connect.

10.10.1, when I posted. Last night I installed 10.10.2. It got hung up on the "Restarting..." (w/App Store logo) screen for over 2 hrs, so I let it run overnight. It was still stuck in the morning so I just shut it down. After restarting, everything looks fine (cautiously optimistic)! There is only ONE instance on the network!! I read some tips in other forums and the simplest one I used, which wouldn't do more harm than good, was to turn off my air printer during the reboot. I am good for now and will repost if the problem returns. William Lloyd how long since you updated have you been multiple-instance-free?

How to get rid of multiple instance of same machine

Hi, I have an issue with my MacPro as I have multiple instance of the same computer. Let me explain : My machine appears as MacPro. but sometime it connect as MacPro (2), or MacPro (3) and so on... I now have MacPro (11). This happens when I get problem with my network... it reconnect the machine with a new name... Big deal you'll tell me... let it be that way and carry on... But Here is where I have a problem : Third party application such as SpeedDownload see all those Instance as Multiples machines and now it won't open because it tells me that I only have a licence for one computer and that the software is installed on multiple computers as MacPro, MacPro (2), MacPro (3), ... and MacPro (11).
Is there a way I could get rid of all the other "Instances" and only keep on machine which would be MacPro?
Thank You,
Martin B.

Multiple instances of same component become non-editable

I have created a simple component for authors to add links. They enter anchor text, link destination, title attribute, via textfield. They set the target attribute via a dropdown list, xtype=selection. The issue we run into, is that if the author has entered multiple instances of the same component on a page, the dropdowns become non-editable after they are set the first time. They cannot be edited changed until the page edit view/content finder is closed and reopened.
Scenario:
1. User drag/drops component
2. User makes selection from dropdown xtype=selection
3. User drag/drops same component again to allowed parent
4. User make selection from dropdown xtype=selection in second instance of component
5. User can no longer change the selection in either instance of the component without closing and reopening edit view/content finder.
6. User closes and reopens edit view/content finder.
7. Again, both instances of the dropdown xtype=selection become non-editable after first selection of an option until the edit view/content finder is closed and reopened.
When there is only one instance of the component on the page, the drop downs/xtype=select remain editable at all times.
In addition to this particular scenario, I've had to work around some other issues of multiple instances of a component, where only one instance on a page works at all, the data gets crossed/jumbled between instances of the same component, etc.
My question is first, how might I solve for the scenario fully called out in this question? Secondly, is there some methodology to making multiple instances of the same component track themselves individually, work together on the same page, play nicely with each other?
Any assistance is appreciated.

Using request scope would be a workaround.
I'm looking for view distinct state for the associated component tree for the session (i.e. managed bean state, whether its separate instances of the bean or copies of serialized state I don't care)
My views require conversational-like state handling that I don't want stored on the client.

Registering multiple iPods on same computer

I currently have a 4G 2nd generation iPod that is registered to our computer. My husband just received a 4th generation iPod. Can you register multiple iPods onto the same computer?
My other question is if you purchase a used iPod, how do you register that and is there anything else we should consider when looking at purchasing a used iPod?
Thanks for any help.

Can you register multiple iPods onto the same computer?
Yes. Register each iPod as if it was the only iPod being used on that computer.
My other question is if you purchase a used iPod, how do you register that
If iTunes doesn't give you the option of registering it, click here and fill out the forms.
and is there anything else we should consider when looking at purchasing a used iPod?
Restore it when you connect it to the computer.

Multiple ipods on same computer?

Is it possible to download music onto two separate ipods using the same computer? I don't mean at the same time.
I want to get an ipod for myself, but would like to be able to download my CD's and not have to have my wife's songs/CD's on my ipod.
I'm not sure this explains what I want to do, but I'll use it as a departure point.
I appreciate any help you can provide. Thanks.

Home sharing to Apple TV with multiple users on same computer

I have two different users on the same computer. To facilitate sharing their music and movies to eachother, they are each using Home Sharing with the same Apple ID. As long as both users remain logged in, this works with no problem. Except for Apple TV. The Apple TV can see each library, so they both show up in the list under Computers, but only one is accessible. It's either the first one that broadcast itself, or the first one that Apple TV connected to, I'm not sure which. But, once that's established, the second library will remain in the Computers list, but any attempt to connect to the library will fail. It appears there is a limitation that Apple TV can only connect to a single library per physical computer, even though it can tell there are multiple libraries there.
Does anyone have any idea how to work around this without consolidating the libraries? Being able to connect to multiple libraries is the goal, not consoludating them.

I don't have that set up anymore, but used to. I had no problems sharing from either library. Of course it may have changed since I used it, but wouldn't see why.
